This tiny .bat file allows you to easily make demos launchable. Once the .bat file has been associated with the .dmo filetype (Control Panel/Folder Options), you can then double-click on a demo, or tell your browser to launch one that it has just downloaded, and the .bat script will then play the demo in Sauerbraten.
The file should be placed in the main Sauerbraten directory (the one containing sauerbraten.bat).
IMHO this file would be a good addition to the distribution.
